Evaluation of the components of the proposed automated DSVR reconstruction pipeline on 5 severe rotation and translation motion datasets with respect to the % proportion of rejected slices and 2D NCC between simulated and original slices in all stacks and only the excluded stack. The investigated scenarios include: (i) Steps I+IV; (ii) Steps I+II+IV; (iii) full pipeline: Steps I+II+III+IV. The results are statistically significant with p < .001 for comparison between (i) vs. (ii) and (iii) scenarios and with p < .01 for (ii) vs. (iii) comparison. Step I is thorax localisation, Step II is reorientation to the atlas, Step III is stack selection and average template generation and Step IV is DSVR reconstruction.

Scenario	% of rejected	all NCC	excl. NCC
I+IV	64.7 ± 5.3%	0.579 ± 0.058	0.550 ± 0.218
I+II+IV	51.6 ± 8.0%	0.728 ± 0.090	0.705 ± 0.105
I+II+III+IV	37.8 ± 9.1%	0.834 ± 0.028	0.809 ± 0.058
